I'm no tty* expert but after vacation, I realised /etc/ttys has been modified.

diff /etc/ttys:

I have no idea why somebody would have set these differently for 10.x vs 12.0R but maybe 
this will help future users.

I did try editing this manually and then `pkill -HUP 1` in case that fixed it interactively,
but no such luck, a reboot was required.
